Yl. Leu et al., THE CONSTITUENTS OF THE STEM AND ROOTS OF ARISTOLOCHIA-FOVEOLATA, Journal of the Chinese Chemical Society (Taipei), 45(4), 1998, pp. 539-541
One new aristolactam glucoside: aristolactam-Ia-N-beta-D-glucoside tog
ether with seventeen known compounds were isolated from die fresh stem
s and roots of Aristolochia foveolata. Their structures were determine
d by spectral and chemical methods. Among seven aristolochic acid deri
vatives, five were determined to be salt forms by IR and H-1 NMR metho
ds.
